Definitions

  • the invention relates to containers, and in particular to collapsible containers which may be used for the transport of various items.
  • One application of the invention is the secure transport of postal items from and between sorting offices and provides for the ready transport of those items between offices after they have been sorted.
  • the mail On arrival at the it's destination the mail is removed from the bag and then re-sorted for particular sub-divisions of the area to which it has been sent (for example: a particular postman's walk, blocks or more detailed postal and zip codes).
  • each carrying mail are placed in a large container, usually of metal, which is used to carry all the mail items to be taken from one particular Post Office to another at which the mail in the trays may again be sorted for delivery.
  • This proposal substantially reduces the cost of sorting the mail but requires the use of trays which are costly to produce and heavy, and the use of containers (for the trays) which are costly, heavy and bulky. The result therefore is that the transportation cost of the trays and the containers - both when full of mail and when empty - is significant.
  • DE-U-9107339 discloses a wheeled container having a rear wall, one side wall fixed rigidly to the rear wall and extending normally thereof and another side wall which is hingeably coupled to the rear wall and moveable between positions in which it lies parallel to, and extends generally normally of, the rear wall.
  • the container is further provided with at least one floor pivotally moveable from a position parallel to the rear wall to a position extending normally thereof.

  • a container embodying the invention is shown in Figure 1 to comprise a flexible fabric (e.g. woven polypropylene) container part 80 held generally in a cuboid shape in a frame 82.
  • a flexible fabric e.g. woven polypropylene
  • Container part 80 comprises a back wall 84, side walls 86, a top wall 88 and a front wall in two parts 90 and 92 as shown.
  • the two parts 90 and 92 are releasably attachable one to the other by a zip fastener 94.
  • the top wall 88 of the container is formed integrally with the back wall 84 and is releasably attachable to the upper margins of the side walls 86 and the front wall parts 90 and 92 by zip fasteners 96 as shown.
  • the fabric container part 80 is provided with a base wall 98 in the form of a base support element - a pocket the margins of which are stitched or otherwise permanently attached to the lower margins of the side walls 96 and the front wall parts 90 and 92 as shown at 100.
  • the pocket 98 includes two generally rectangular rigid planar pieces 102 which extend the width, (as viewed in Figures 1 and 2), and substantially half the depth of, the container fabric part 80.
  • the container back wall 84 also carries three sets of side support elements 104A, 104B and 104C.
  • Each set of side support elements comprises three elements 106, 106' and 106'' stitched onto the fabric of the container at the side edges of the back wall (106 and 106'') and substantially at the midpoint of the back wall 106').
  • Each side support element 106 comprises a fabric pocket in which there is located a rigid planar piece 108.
  • the elements 106 are stitched onto the fabric of the back wall 84 to form a hingeable connection for each element 106 so that it may be moved from a position in which it lies parallel to the back wall 84 to a position in which it extends substantially normally thereof.
  • the axes of the hingeable connections between the back wall 84 and the elements 106 are, as can be seen, substantially parallel and, within each set of elements 104A, 104B and 104C are in register - that is to say they are mounted at the same height on back wall 84.
  • Each of the elements 106 may be held in a position in which it lies substantially parallel to the back wall 84 by any suitable means - however it is preferred that cooperating attachment patches 112 of hook and eye material provided on the back wall 84 and the elements 106 (or on the facing surfaces of the elements 106 when they overlie one another) be used to hold the elements 106 in a position substantially parallel to the back wall 84.
  • any mail placed in the compartmentalised tray formed by the elements 106 of the lowermost set of elements 104A and the base wall 98 of the container will be held in the particular orientation in which they are placed within the container.
  • the extent of the side support elements 106 is substantially equal to the extent of the base wall 98 of the container.
  • Each of the other sets of elements 104B, 104C attached to the back wall 84 comprises, in addition to the side support elements 106, 106' and 106'' a base support element 114B and 114C comprising a pocket the size of which is substantially equal to that of the base wall 98 and which contains a single, rigid, planar piece 116.
  • Each of the base support elements 114 is normally held in a position lying substantially parallel to the back wall 84 once again making use of cooperating attachment patches 112, the attachment patches being provided on the upper surface of the base support elements 114 (as viewed in Figure 1) and the surfaces of the elements 106 spaced from the back wall 84 when the elements 106 lie parallel to the back wall.
  • the base support elements 114B of the set of elements immediately above the lowermost set of elements 114A is movable from the position shown in Figure 1 - that is to say lying substantially parallel to the back wall 84 to a position in which it overlies and rests upon the uppermost edges of the side support elements 106 of the lowermost set of elements 104A.
  • the base support elements 114B of the set of elements 104B may be pulled away from the back wall 84 and allowed to rest on the uppermost edges of the elements 106 of the set of elements 104A.
  • the elements 106 of the set of elements 104B may be moved from positions in which they lie parallel to the back wall 84 to positions in which they extend normally thereof forming another compartmentalised tray to which items of mail may be passed.
  • Further compartmentalised trays may be provided as the container is filled by moving the elements 114C and 106 of the third set of elements 104C until the container is full.
  • the container may be closed and sealed by moving the top wall 88 until it overlies the compartmentalised trays and, using the zip fasteners 94 and 96, attaching the top, side and front wall together.
  • Eyelets may be provided, as indicated at 118 in the fabric of the top wall 88 and in the front part walls 90 and 92 through which a piece of rope, twine or string may be passed to seal the container.
  • Loops of material 120 are provided at the upper margins of the back and side walls enabling the fabric container part to be held on hooks 122 in a generally open position, supported in the frame 82.
  • the container may be lifted from the frame and used to transport mail to another office at which it will again be sorted.
  • the filled container may then be opened allowing mail to be taken from each of the compartmentalised trays in turn and passed directly to a mechanical sorting device - it having been held in a particular relative orientation during transportation.
  • compartmentalised trays are emptied from the top down and as each is emptied the side support elements 116, 96 and base support elements 104 are moved from positions in which they extend normally of the back wall 84 to positions in which they overlie one another and lie substantially parallel to the back wall 84.
  • the container may be lifted from the frame and folded substantially as shown in Figure 3.
  • the two rigid pieces 102 forming in the base wall 98 of the container allow that wall to fold substantially about its mid line and thereafter the remainder of the container (with the zip fasteners 94 and 96 closed) may be folded - the side walls folding upon themselves bringing front and back walls together and holding the sets of members 104 in parallel relationship with the back wall.
  • the folded fabric container part may then much more readily be transported than if it were rigid and/or if the compartmentalised trays formable in the fabric container part were rigid and incapable of disassembly.
  • the fabric material of the fabric container part including the pockets is desirably woven polypropylene and the material forming the rigid planar pieces within the support elements is desirably polypropylene boarding. If made of polypropylene the overall weight of the container is very substantially reduced and thus the cost of transporting the container (both when full with mail and when empty) is markedly cut.
  • Figure 4 shows a container frame for use in a container embodying the invention to comprise a rectangular base frame 130 of 25mm 2 metal tubing on one face of which, at the four corners of the base frame, are provided caster wheels 132.
  • the side frames 134 and 136 are generally of the same form and each includes a pair of upstanding posts, 134A, 136A which, it is to be noted, extend to different heights above the base frame 130, the posts 134A (which are the same height) being shorter than the posts 136A (which again are of the same height).
  • the side frames 134 and 136 include further posts 134B and 136B the lowermost ends of which (as viewed in the Figure) are hingeably connected to the tops of the posts 134A and 136A.
  • the free ends of the posts 134B and 136B are joined by side bars 134C and 136C as shown.
  • the posts 134B of the side frame 134 are longer than the posts 136B of the side frame 136 by an amount equal to the difference in the lengths of the posts 134A and 136A so that when the posts 134B and 136B are upright (as viewed in Figure 4) the side bars 134C and 136C are at substantially the same height above the base frame 130.
  • the side frames 134 and 136 are completed by a number of runners 138 extending between the pairs of posts 134A and 134B, and 136A and 136B as shown.
  • the runners 138 are provided at spaced intervals above the base frame 130 and each is generally L-shaped in section over most of its length but has a central part 138' which is cut out.
  • Cross bar 140 has two spigots 142 upstanding therefrom as shown.
  • the side bars 134C and/or 136C may be provided with one or more handles (not shown) to ease movement of the framework and further, if desired, the framework may be provided with a braking system (not shown) for the caster wheels 132.
  • Figure 5 show a fabric container part to be supported in the framework to comprise a back wall 150 formed with a series of pockets 152 which are sealed (for example by stitching) after an appropriately shaped rigid planar element 152' was placed in each of them.
  • each of the pockets 152 is such that its width (as viewed in Figure 5) is substantially equal to the width of the base frame 130 as measured between the side frames 134 and 136 and its height is substantially the same as the spacing between the runners 138 carried in the side frames 134 and 136.
  • the side edges of the back wall 150 of the container are further provided with attached pockets 154 each having the shape shown.
  • Each of the pockets 154 has again been sealed after a rigid planar piece 154' of the appropriate shape has been inserted in it.
  • each side pocket 154 is substantially equal to one half of the length of the side support bars 134C and 136C.
  • the lowermost edge of the back wall 150, below the lowest pocket 152 has attached to it a further fabric piece 156 comprising three pockets 158, 160 and 162 each of which has a rigid planar piece (158' 160' and 162') placed in it and is thereafter sealed (for example by stitching).
  • the height (as viewed in Figure 5) of the pockets 158 and 160 is substantially equal to one half the length of the side support bars 134C and 136C and their width - as can be seen - is substantially the same as the width of the pockets 152.
  • the width of the pocket 162 is again substantially equal to the width of the base frame 130 in which the container will be mounted and its height may be half that of the spacing between the runners 138 (as shown) or as desired, but not exceeding the spacing between the runners 138 in the side frames 134 and 136 of framework.
  • Fabric pieces 156 are also attached (for example by stitching) to the back wall 150 as indicated at spacings substantially equivalent to the spacing between the runners of 138 in each of the side elements 134 and 136 of the framework. It will be noted that the points of attachment of the fabric pieces 156 (forming pockets 158, 160 and 162) is between the pockets 152 formed in the back wall.
  • the upper edge of the back wall 150 has loops of fabric 164 attached thereto as shown.
  • Attachment patches or strips of material similar to those described above with reference to the first embodiment are then applied to the fabric of the container as shown in Figure 5 at 166.
  • Those areas where the attachment patches are applied to the viewable, front, surface of the fabric (as seen in Figure 5) are indicated by the letter O, whilst the letter X indicates where attachment patches are applied to unseen side of the fabric (as viewed in the Figure).
  • attachment patches applied to the container shown in Figure 5 is twofold; firstly, the patches enable the elements of the container to be held folded against the back wall 150 of the fabric container part and secondly the patches will, as described below, enable the fabric container part to be securely supported in the framework.
  • the side pockets 154 are first folded about the side edges of the back wall such that the attachment patches at their outermost ends come into contact with the patch located generally centrally of the front surface of the back wall 150.
  • each of the pocket 162 may be folded about its join line with a pocket 160 so that the attachment patches on their front surfaces will engage and hold the pocket 162 against the pocket 160. Thereafter the pockets 160 and 158 may be folded - again about their join line so that the patches on their back surfaces engage to hold the two together. In this condition the pockets 158, 160 and 162 are now folded and in close contact with one another.
  • Figure 6 shows the framework of Figure 4 supporting the fabric container part of Figure 5. As shown in Figure 6 the fabric container has been partially unfolded or extended so that the way in which it is supported in the framework may be more clearly seen.
  • the fabric container part is placed in the framework with the side pockets 156 and pockets 158, 160 and 162 held against or parallel to the back wall 130.
  • the top edge of the back wall 130 is then grasped and lifted upwardly so that the loops of material 164 on that edge can be placed over the spigots 142 on cross-bar 140. It will be appreciated that the cutout portions 138' of the runners 138 enable the container to be unfolded and lifted up between the side frames 134 and 136 in this operation.
  • the lowermost fabric piece 156 is lifted from its engagement with the side pockets 154 and the pockets 158, 160 and 162 disengaged from one another.
  • the fabric of the container is then manipulated so that the pockets 158 and 160 lie flat and the attachment patches on their lowermost surfaces (as viewed in Figure 6) engage the patches provided on the base 130 of the framework. It will be seen the pockets 158 and 160 now form a base support element resting on the runners 138.
  • the pocket 162 is then folded up so that its outermost ends engage the attachment patches on the surfaces P of the side support posts 134A and 136A forming a base support front wall part.
  • the side pockets 154 are then dis-engaged from their contact with the back wall 150 and folded out until the attachment patches thereon engage the strips of material 170 provided on the surfaces Q of the side posts 134A and 136A.
  • a tray has been formed in the bottom of the framework by the container which covers half the base frame.
  • This tray has an outer wall (formed by the pocket 162) which is of any desired height but preferably, as shown in the drawing, approximately half of the depth of pocket 154.
  • the tray may be filled with any desired object - one particularly useful application of the storage device would be if the tray were filled with mail.
  • Placement of mail oriented in a particular sense in the tray will enable that mail to be moved, in the storage device, without the orientation of the mail items changing.
  • a second tray may be formed in the framework by bringing away from the back wall 150 of the container the pockets 154, 158, 160 and 162 of the fabric piece 156 next above that which has been unfolded.
  • This second fabric piece is in substance the same as the manipulation of the first with the pockets 158 and 160 being supported at the sides of the framework on the upper, attachment material covered, surfaces of runners 138.
  • the container may be fully extended within framework by detaching the constituent parts of the other fabric pieces from the back wall of the container and bringing them into engagement with the members of the framework in the same way.
  • the container occupies one half of the framework and it is envisaged that a second container, similar to the first, will be provided in the other half of the framework.
  • That other container will be supported in the same way as the first container - that is to say the loops on material 164 formed on the upper edge of the back wall of that other container will be engaged by the spigots 142 on the cross-bar 140 of the framework.
  • the container After use - when the container is empty and no longer required - it may be contracted within the framework by detaching the upper edge of the back wall 150 from the cross bar 140 of the framework (after having folded the various elements of the fabric pieces such that they lie against or parallel to the back wall 150). Thereafter the back wall may be folded down such that the fabric container part rests on the base of the framework.
  • the cut out sections 138' of the runners 138 enable the fabric container part to be folded down onto the base of the framework.
  • the or both containers have been so folded down it is possible to disengage the cross bar 140 from its engagement with the side bar 134C (or 136C) and allow the cross bar to fall down such that it lies parallel with the side support 134 (or 136).
  • the posts 134B are pivoted around their hinged connection to the post 134A so that the upper part of side support 134 lies across the base of the frame on top of the folded fabric container on the base.
  • side posts 136B are similarly pivoted around their hinged connection to the posts 136A such that the upper part of side support 136 overlies and rests upon the side part 134 as shown in Figure 7.
  • parts of a lower collapsed framework are shown supporting parts of another collapsed framework stacked thereon. References to the upper collapsed framework are distinguished by being prime.
  • the posts 134A and 136A are provided with short extensions 134D and 136D which are L-shaped in section and which permit the ready stacking of one collapsed framework upon the other.
  • the base of the framework will be provided as a solid panel forming the base of the container the lowermost fabric piece of the container may then be omitted if desired.
  • side frames may be provided as solid panel members having runners formed on their "inner" walls.
  • slots will be provided in the panels to accommodate the wheels 132 of an upper framework stacked on a lower one.
  • the trays formed in the framework by the pockets 154, 158, 160 and 162 may be provided with divider walls.
  • Such divider walls would comprise pockets substantially the same size as the pockets 154 and containing a rigid planar element.
  • the pocket would be stitched along one of its shorter edges to the back wall 150 of the container and be pivotable from a position in which it lies against the back wall to a position in which it extends generally normally thereof and parallel to the side support elements 154 when the fabric container part is extended.
  • Means may be provided (perhaps in the form of cooperating studs) on the pocket 162 to generally hold any such divider wall in a desired position.
  • the container described with reference to Figures 4 to 7 may be used to form trays the heights of which vary from those shown. For example if a set of pockets 154, 158, 160 and 162 were left folded against the back wall 150 of the fabric container part then the height of the tray immediately beneath those pockets would be substantially doubled.
  • the fabric container part may be formed with one or more of the fabric pieces 156 omitted so that trays of different heights may be formed when the fabric container part is extended in the framework.
  • runners 138 provided in the framework may, of course, be varied from that shown.
  • the arrangement comprises a series of inter-connected pockets in which a rigid planar pieces are placed.
  • the fabric is woven polypropylene and the rigid planar elements are of moulded polypropylene.
  • the container may be made of any rigid material the parts of which are hinged or otherwise pivotally interconnected one to the other so that the container may adopt the extended form shown in the Figures.
  • a particularly useful modification provides that the container be made of a rigid, lightweight, plastics material and the pivotable interconnections are formed by having fold lines or living hinges of reduced thickness material at the appropriate locations.
  • the further pieces 156 attached to the back wall 150 of the container would, in this arrangement, be welded thereto.
  • Figure 8 shows a fabric container part similar to that of Figures 1 and 2 supported in the framework of Figure 5 and similar parts are given the same reference numerals.
  • the fabric container part of Figure 8 differs from that shown in Figure 1 by being provided with loops of material 126' for engaging the spigots 142 on the cross bar 140 and a pair of hook members 121 at the top of each side wall 86 for engaging the side support bars 134C and 136C of the framework to hold the fabric container part open in the framework.
  • the top wall of the fabric container part is now in two parts 96' formed as extensions to the front wall parts 90 and 92 and these two top parts are attachable one to the other and to the back and side wall by zippers 123. Finally, the top and base walls of the fabric container part are sized to fit half the frame of Figure 8.
  • the described embodiments provide for the ready and secure transport of postal items in and between postal sorting offices, and which also enables the cost of sorting the mail and of transporting mail containers (when both empty and full of mail) to be reduced in comparison to traditionally used methods and in comparison with more modern proposals.
